Avalanche

Avalanche is an EVM-compatible proof-of-stake layer-1 network engineered for multi-chain scalability and sub-second settlement. Built around a primary architecture split into distinct functional chains, the platform enables builders to deploy standard Solidity contracts on its execution chain or launch custom sovereign networks called Avalanche L1s.

Founders and backing

Ava Labs developed the protocol, founded in 2018 and headquartered in New York. The founding team includes CEO Emin Gün Sirer, a former computer science professor at Cornell University known for distributed systems research, alongside fellow Cornell researchers Maofan 'Ted' Yin as chief protocol architect and Kevin Sekniqi as COO. Ava Labs and the Avalanche Foundation have raised $278M across private rounds and public token sales, with backing from Andreessen Horowitz, Polychain Capital, and Initialized Capital.

Architecture and core mechanics

The network operates a heterogeneous primary network divided into three interoperable environments: the Contract Chain (C-Chain) for EVM-compatible decentralized applications, the Platform Chain (P-Chain) for coordinating validators and staking, and the Exchange Chain (X-Chain) for asset creation. Transactions on the C-Chain execute using standard Ethereum tooling, while consensus relies on the Snowman protocol family for rapid probabilistic finality. Developers can also spin up sovereign Avalanche L1s with independent validator parameters, dedicated gas tokens, and tailored compliance rules, linking them across the ecosystem via Avalanche Interchain Messaging.

Fees and network requirements

Gas on the primary C-Chain is paid in the native AVAX token, which is burned upon transaction execution. Staking rules were adjusted in September 2026 under the Helicon upgrade, establishing a 48-hour minimum staking period, auto-renewed staking parameters, and a 90% validator uptime requirement. For sovereign L1 networks, the Avalanche9000 upgrade introduced under ACP-77 eliminated the previous 2,000 AVAX validator lockup requirement, substituting it with a continuous fee structure paid to the P-Chain.

Track record and real-world adoption

Avalanche launched its mainnet on September 21, 2020. By October 2026, the primary network held over $585M in total value locked, alongside $1.24B in stablecoin market capitalization and $1.08B in active real-world asset value. Public institutions and enterprises have implemented the infrastructure for operational identity and records; the UAE Federal Digital Government Authority uses the network for its UAEPASS Digital Vault, and Dubai's DIFC Courts began anchoring verifiable legal filings on-chain in October 2026.

Risks and operational trade-offs

Operating custom L1s requires ongoing validator coordination and continuous fee payments to the P-Chain. While EVM compatibility simplifies onboarding, interchain operations across distinct subnets rely on aggregate BLS signature validation, introducing bridge and messaging security dependencies. In August 2022, whistleblower platform Crypto Leaks raised allegations concerning litigation pacts between Ava Labs and an external legal firm, claims that company executives publicly denied.
